I have been awfully quiet on my blog lately. I think that is because I have been busy with other things, like my garden and stuff like that. There are some ‘techie’ thing I have done in the meantime, though, I have submitted a couple of abstracts for Tech14. Hope at least one of them […]

There is a ‘rule’, I think it was created by Tom Kyte, stating: If you can do it in SQL, do it in SQL. I came across some code the other day that makes perfect sense to do then you are running an Oracle 10g (or earlier) instance. I rewrote the code to use only […]

I have reviewed the latest edition of Oracle PL/SQL Programming. This is not a book, at least for me, that I would read front to back. I use it mostly as a reference, but the great thing about this book is that you can also use this book to learn programming PL/SQL from scratch.

After a presentation by Lucas Jellema I decided to try something with types in Oracle. One of the issues posed in this presentation was that the type cannot include self-reference. Neither direct nor indirect.

This is kind of weird IMHO, because you have to uppercase the value you are looking for. I was wondering why we are not using the LOWER() function. I put this question on Twitter the other […]

Just back from a full week in San Antonio for KScope12. I really had a good time. ODTUG provides us with the best conference for developers in the world. Seen some great sessions, met up with some old friends, made a lot of new ones, met in real life with some people I knew only […]

In my current project I wanted to add some timing to the logging the code already does. So I started my search for a good timing package. My first idea was to download PL/Vision and use the timer that is in there. Installing this was not as simple as I hoped it to be. The […]
